My invention relziies to :i new and useful improvenient in grinders lor vulves :ind the like, rind has lor its Ohject t0 provide ii simple :ind effective iiieelniiiisin for operating i grinding disk wlierehy vulve fsrenis iiiid the like inriy he properly ground hy first revolving the disk iii one direction and then in the other, lifting the grinding disk from the sont poing ground :ind replacing it thereon.

With these ends in view, this invention Consists in the details of construction rind eoinliiinition ol elements hereinafter ser. forth and then speeitieiilly designated by the claims.
